As promised, here is my follow-up video where I show you how to install new TPMS sensors in a tire that is already mounted on a rim. Do this if you are replacing an existing TPMS sensor, or if you are adding a sensor where you had a regular rubber valve before.
I am installing Autel MX Sensors in my winter tires. In my previous post, I showed you how to program these sensors. If you missed that, read it here: http://www.gabeshacks.com/2016/10/how-to-clone-and-program-new-tpms.html
Here's a tip I learned later: Drive a nail through the two boards into the small piece so they don't slip.
